1 Corinthians 11:1-6

Follow my example, as I follow the example of Christ. I praise you because you remember me in everything, and you follow closely the teachings just as I gave them to you. But I want you to understand this: The head of every man is Christ, the head of a woman is the man, and the head of Christ is God. Every man who prays or prophesies with his head covered brings shame to his head. But every woman who prays or prophesies with her head uncovered brings shame to her head. She is the same as a woman who has her head shaved. If a woman does not cover her head, she should have her hair cut off. But since it is shameful for a woman to cut off her hair or to shave her head, she should cover her head.
